PMI PERFORMANCE CHEMICALS
PMI 107 is an anionic surfactant. It is a single product which maintains the homogeneity of crude as it moves through the production and transportation system. It has an affinity with steel which means that it coats the contact surfaces of pipes, tanks and all plant and equipment with which it comes into contact.
Because the crude is kept in an homogeneous state as it flows it has no opportunity to drop waxes and corrosive matter thereby preventing accumulations of waxes, asphaltenes and preventing corrosion damage. Application is by low level injection as far upstream as possible so that the effects of the treatment can pass right the way through the system.
Existing wax build up is gradually reduced as the PMI 107 migrates along the contact surfaces. The removal of waxes and sludges overcomes the problems of dead spots where SRBs can normally thrive.
By removing blockages in pipelines and sludge build up in storage tanks, productivity is immediately improved without expensive down time and the reduction of problems associated with corrosion avoid costly maintenance programmes.
PMI 107 and its predecessors have been demonstrably and successfully used in Canada, UAE, Kazakhstan, Thailand, Indonesia and elsewhere over the past 20 years
PMI TC2 is a powerful solvent all of whose active ingredients derive from Oranges. This is classified as a non-hazardous solvent (except for the normal issue of not allowing inhalation into the lungs). It is immiscible in water so cannot cause emulsions. It will dissolve all petroleum hydrocarbons, whatever their condition. It is widely use for clearing up legacy waste problems, oil spill, heavy contamination in tanks, pipelines and any structure where immediate results are required.
It is used by ADCO for clearing wax plugged wells, Saudi Aramco for tank cleaning Bonoco for tanks cleaning and wellbores among many others. It is used for foreshore cleaning in the event of marine oil spill
PMI SC3 is a highly effective H2S scavenger. It works immediately on contact and converts the H2S irreversibly to a harmless salt. SC3 is applied as far upstream as possible by continuous dosing wherever H2S is present or anticipated. Where the gas occurs in an open source it is neutralised by spray application.
PMI SC4 is a mixture of organic and inorganic acids and solvents. It is a multipurpose polymer, carbonate particle and scale dissolver with applications in open holes and as a cake breaker. It has built in corrosion sequestration and demulsifiers, and is used to scour metal ions.
SC4 is widely used by Saudi Aramco and others in combination with PMI TC2 where oily deposits need to be removed prior to descaling activity in disposal wells.
PMI SC5 is a combination of ammoniated salts and acids. It is a multi-purpose sulphide scale and carbonate cake remover. It is used to recover blocked injection and production streams in injection wells systems. Widely used in conjunction with PMI TC2 where oily deposits need to be removed prior to descaling. Widely used by Saudi Aramco in disposal wells
PMI SC6 is an oxygen scavenger. It is a widely used product in the industry based on DEHA and is applied by injection.
PMI SC7 is a glutaraldehyde based material which is widely used in the industry as a biocide to deal with SRBs (sulphur reducing bacteria) which are serious causes of corrosion. This material is largely made redundant in systems utilising PMI 107 because the conditions which are congenial to SRBs are eliminated by 107. However PMI 107 has no biocidal properties, so PMI SC7 might prove to be a necessary precursor to an application of 107.
